Base I comprises a main casting I1 adapted to engage the floor at spaced points over a substantial area and thus provide a sturdy support for the unit, while, at the same time, permitting the unit to be shifted about whenever it is desired to changeits location in a factory as when the sequence of operations in a line production system is altered. In a recess I8, provided in the casting I1 (Fig. 5), there is mounted a foot treadle I9 (Fig. 1) having vertically disposed downward extensions'2ll and 2I mounted on and adapted to rock with shaft 22 journalled in portions 23, 24 and 25 of the base casting. The right hand end portion of the shaft (Figs. l and 5) is bent at right angles to the main axis of the shaft as indicated at 25. The extreme end of this portion of the shaft is flattened and apertured to receive the bent over end of a vertically disposed rod 21 which extends upwardly through the column II to a point in the vregion of the support member I3 where it is connected to certain devices, to be hereinafter described, for the purpose of operating the clutch walls 24 and 25 of the base casting there is mount-4 ed'a second foot treadle 28 (Figs. 1 and 5) whichV is-pivoted upon the casting by means of a pivot pin 29. Suitable clearance is provided between treadle 28 and the shaft 22 to permit rocking of the treadle without interference with the shaft. In its rear portion the treadle 28 carries an an`- gularly disposed rod 30, the outer end of which is flattened and apertured to receive the lower bent over end of arrod 3| which extends upwardly through the hollow column I I. This rod is preferably formed in two sections to permit variation in the length of the link which it provides. At its upper end rod 3I is connected, in a manner to be described, with devices for lifting the presser bar -tain extent within sleeve 32 to vary the overall height of the support. At an intermediate point along the column thereis secured thereto a collar 33V which may be clamped to the column in any suitable way, as by means of set screws 34. Above the collar 33, there is mounted on the column a 'hub or collar-like portion 35 of the bracket I2.

Set screws 36 may be provided for securing the hub 35 to the column. This arrangementis such that the bracket I2 may be adjusted both axially and'angularlyin relation to thecolumn. It will be understood that the collar 33 assists in making the desired adjustments of the bracket, since it will carry the load of the bracket when the set screws 3B are loosened and, for example, permit the bracket Vto be shifted angularly about the column without varying its axial position in relation to the column. Integral with the hub 35 is a forwardly and upwardly extending arm 31 which, as shown in Fig. 2, may be inclined at an :angle of about 30 to the vertical. This arm is preferably enclosed on three sides, i. e., its front and two side faces, but is open along its upwardly and rearwardly presented face, as indicated by the edges 38 in Fig. 3. It thus forms an open channel which conveniently receives certain of the operating connections. At its upper end the arm 31 carries a pair of laterally extending arcuate supports 39 which present alined, upwardly facing, concave, bearing surfaces. Each of these extensions .is provided with a circumferentially extending, elongated, arcuate slot 40 adapted to receive the shank of abolt 4I which is secured to and extends downwardly from a depressed portion 42 of the support member I3. The under face of portion 42 is convexly curved and adapted to seat in the concave faces of the supports 39. As best shown in Fig. 6 the downward projection 42 is provided with apertures 43 which receive the Shanks of the bolts 4I, the latter being suspended by their heads from the portion 42. Preferably the radius of curvature of the convex face of the portion 42 is slightly greater than that of the concave upper faces of the supports 39 so that only line contact, along two spaced lines, occurs between these surfaces. This facilitates rocking of the projection 42 about the supporting element 39. If desired, however, these surfaces maybe Vformed to't with full surface contact, in the manner of a journal in its bearing. It will be understood that the bolts 4I serve to clamp the projection 42, and hence the support member I3, in any desired tilted position, within the limits permitted'by the slots 40, in relation tothe upper end of the arm 31.

Each of a plurality of bosses 44 (Fig. 6) suitably located on the support member I3, is provided with a screw threaded opening adapted to receive a screw for securing the table board I4 to the support member. It will be understood that the table board is provided with a relatively l large opening in the region of the hinges I5a to receive thebase portion of thesewing machine.H The latter may be of any suitable construction. That illustrated is of the type shown lin thepatent tcA Quist No. 2,414,168, granted Ydicated.

The main shaft of the sewing machine, which extends longitudinally of the overhanging arm, is provided at its end, outwardly of the frame of ythe machine, with a combined handwheel and pulley 41 through which the machine is driven. Member 41 is connected by a belt 48 with a pulley 49 carried by .the driven element of the motor and-clutch driving unit I6. An opening 50 extending through the table board and an alined opening 5I in the support member I3 permit ,the

passage of the belt through these parts. Provision is made for suspendingthe driving unit I6 from the underside of the support. member I3 in such a way that the driving unit may be shifted bodily in a direction transverse to its axis. For

`this purpose a pair of bolts 52, cooperating with lugs or feet 53 formed on the frame of the driving unit (Fig. 3), pass through elongated slots 54 and 55 in the support member I3 (Fig. 6). Similarly a bolt V5I, made accessible by a cutout 51 in the edge of the table board, passes through an asuman elongated opening 581 in thesupportmember I3 and is received by an opening in a lug or foot 591 formed on the frame of the unit I6. Upon loosening the several bolts 52 and 56, the unit IB may be adjusted in a direction transverse to its axis, for belt tightening` purposes and the like, and it may be set in adjusted position by tightening the bolts. Rubber or felt washers or the like are preferably employed around the bolts at the upper and lower surfaces ofV the support member I3 and the lugs 53 and 59 to absorb vibration and deaden any sound that may be generated by the driving unit.

For the purpose of controlling the clutch of the transmitter, the upper end of the rod or link 21 (Fig. 3) is connected with an arm 60 secured to a rock shaft 6I journalled in suitable bearings 62 and 63 on the underside of the support member I3 (Fig. 6). An oppositely extending arm 64 is secured to the opposite end of the shaft 6I and isconnected by a rod 65 with an arm 65 (Figs. 1 and 2) extending outwardly from a collar 61 secured to the clutch shifting sleeve (not shown) of the. driving unit. This unit may be. of any suitable, known construction. That illustrated is of the type disclosed in the Peets et al. Patent No. 2,004,055, granted June 4, 1935. The arrangement is such that, on depressing the treadle I9,

' the rod 21 will be dra-wn downwardly and through the connections described will rock the clutch engaging sleeve of the driving unit to cause the sewing machine to be driven.

An arm 68 (Fig. 6) securedA to a rook shaft B, journalled in a' bearing sleeve 10 carried by the under side of the supportmember I3, is adapted to be connected with the upper end of the rod 3i which is operated by the foot treadle 28. At its opposite end the rock shaft 69 is provided with a transversely extending finger 1l which is connected through a lever (not shown) with a rod 12 (Figs. 2 and 3) connected with an arm 13 extending rearwardly through the frame of the sewing machine. Arm 13 forms a part of the presser bar lifting mechanism (not shown) which may be of any suitable construction, such as that illustrated in the above mentioned Quist Patent No. 2,414,168.

lt will be seen from the foregoing that the sewing machine and its controls are very conveniently disposed in relation to an operator seated in front of the treadles I9 and 28 (Fig. l) thatis, seated at the left in Fig. 2 and facing toward the right of said figure. A very sturdy support is provided for the sewing machine and its driving unit. Moreover, the sewing machine is positioned conveniently over the foot treadle while at the same time a maximum amount of free space is providedbeneath the supporting table so that the operator is free to assume the moet comfortable position. There is nothing to interfere with any part of the operators body nor 'with the free handling of the work to be stitched. The improved supporting structure permits the pedestal or column ii to be located toward the rear of the supporting structure to provide` the freedom of movement indicated. At the same time, provision is made for a variety of relative adjustments of the various parts. The

height of the supporting table I4 may be adof` the4 column II, by swivelling the hub35 about the column. The angular position of the sewing "machine in. relation to` the treadles I9 and 28 may thus be varied to suit the preferences of particular operators` or the requirements of particular operations. So` also the cooperating` arcuate, partial cylindrical surfaces of the elements 3g and' 42 permit tilting of the support member I3: in relation tothe bracket.v i2 to any extent desired within the limits permitted byf the arcuate` slots f2.0; The preferences of various` operators and the requirements. ofv various operations may thus be accommodated to maximum advantage. As has previously been indicated; the driving unit is also made bodily adjustable; in a direction transverse to its axis for belt tightening purposes and the like. As will be best seen in Fig. 2, the slope of the rearward edge of arm 31 is such that the pulley 49 of the driving unit is readily accessible for removal when t .e support member I3 is in its horizontal position.

Referring now to Figs. 7, 8 and 9, another embodiment of the invention is shown. This differs from the first embodiment primarily in the location and arrangement of the driving unit in relation to the sewing machine and its supporttable. The pedestal support comprises a fioor engaging base member 14 having an upstanding collar or sleeve 15 which, in this case, is located toward one side of the base: member but at a point near the longitudinal center line of the base member. This, as will appear later, provides for more direct connections between the treadle and the clutch operating arm of the driving unit and makes the drivingl unit more readily accessible. A tubular column 16 is received by the hub or sleeve 15 and is secured therein, in adjusted position, by means of set screws or the like. A collar 11 is mounted on the column E6 at an intermediate point and secured thereto by one or more set screws. Above this collar the column carries a hub portion 18 of a bracket having an upwardly and forwardly extending arm 19, preferably of the same general construction as the arm 31 of the first embodiment but inclined forwardly at a smaller angle to the vertical. The upper end of arm 19 is provided with, two laterally extending flanges 80, of arcuate frm, presenting upwardly extending concave, partial cylindrical surfaces. Elongated slots 8l extending through the flanges 80 receive bolts` 82, carried by a downwardly extending bearing portion 83 of a plate-like support M. Projection 83 has a convex, partial cylindrical surface adapted to engage the concave upper surfaces of the anges 80. The radius of curvature of the projection 33 is preferably slightly greater than that of the supporting surfaces of the flanges 30 to produce line contact, rather than surface contact, between these parts. As in the first embodiment, however, these surfaces may, if desired, have a journal and bearing relationship. It will be understood that this arrangement, similar to that provided in the :first embodiment, enables tilting of the support member 8d either forwardly or rearwardly to any desired extent within the limits permitted by the slots` 8l. member in any adjusted position.

Secured to the upper surface of the support member' is a table board 85 which may be held in` place by a numberY of screws 85 (Fig. 9). A

sewing machine B1 of any suitable construction, such asthat provided in the, first embodi- Bolts 82 serveto clamp the support nient, is mounted on the table board by means of hinge plates 88. The base portion of the sewing machine is adapted to pass through a suitableopening in the table board and is seated between arms 89 and 90 of the support member 84. A flange provided by a slight extension of the work supporting member of the sewing machine cooperates with the upper surface of the table board, in the region of the opening therethrough, to retain the machine in proper position.

Support member 84 is similar in construction to support member I3 of the first embodiment, but, as best shown in Fig. 9, is of somewhat different configuration in plan. It is provided with a rearward extension for suspending the driving unit 9|. The latter is attached to the support member by a plurality of bolts 92, three being shown, which cooperate with elongated slots 93, 94 and 95 extending transversely of the axis of the driving unit. Table board 85 may be suitably grooved on its under' surface to accommodate the heads of these bolts. The means for attaching the driving unit may be similar to that described in relation to the first embodiment and preferably includes shock absorbing and sound deadening means. A driven pulley 96, connected with the driven element of the clutch of the unit, is connected by a belt 9'1 with a combined handwheel and pulley 9S on the sewing machine. This belt passes through an opening 98 in the table board and a corresponding opening through the support member B4. Elongated slots 93, 913 and 95 permit adjustment of the driving unit in a direction transverse to its axis for belt tightening purposes. Y

The driving unit may suitably be of the same type as in the first embodiment and may include an operating arm |68 extending radially from a clutch engaging sleeve. This arm is connected through the balanced springs shown in Fig. 8 with a rod IBI which extends downwardly through the column 'I5 and is connected with an arm |02 formed preferably as a bent extension of a treadle supporting shaft |93. A treadle |04, which may be similar to treadle I9 of Fig. 1, is secured to th'e shaft |63 for operating the latter to cause engagement of the clutch of the driving unit.

Means for lifting the presser bar may also be controlled by a treadle, as in the first embodiment, but for simplicity it is preferably placed under knee control. For this purpose a knee pad is carried by a rod |05 mounted in a clamp I D'I secured to a rock shaft |08. The latter is journalled in suitable bearings on the underside of the support member 84 and carries at an intermediate point an arm |09 adapted to cooperate, either by a link connection or by a camming action, with a rock lever (not shown) similar to that shown in Quist Patent No. 2,414,168. The opposite arm of said lever is connected by a rod ||0 with an arm ||I extending outwardly through the frameof the sewing machine and connected in the manner disclosed in said Quist ,patent with the presser bar lifting means.

` The embodiment of Figs. 7 to 9 does not pro-.- vide quite as much free space beneath the supporting table as does the first embodiment, but it has the advantages of greater compactness in a longitudinal direction and simpler and more direct control connections, among others.

While several illustrative embodiments of the invention have been disclosed in some detail, it will be understood that various modifications may be made in the construction and arrangement of the various parts. Features disclosed in connectionwith one embodiment may, if desired, be incorporated in the other.
